Application fi1ediApri1 12,1922. serial no 551,867.

State of Ohio, have in'vented'a new and useful Hand-Propelled Vehicle,ofwhich the following is a specification.

This invention relates, to hand propelled vehicles and more particularlyto means for manually driving toy wagons and the like.

The objects of the invention are to pro vide a hand propelled vehicle inwhich, an oscillating movementof the operating lever is transformed intoa continuous rotary motion of the driving axle.

The above and other objects may be at tained by constructing the deviceas illusr trated in the accompanying drawings, in which I Figure 1 is alongitudinal section of'a hand propelled vehicle embodying theinvention; and

Fig. 2,

gim'ilar numerals indicate similar parts throughout the drawing.

In the drawings va'hand propelled vehicle is shown, comprising asuitable truck frame including the spaced, longitudinally disposedmembers 1, upon the forward end of which is mounted a bolster 2, towhich the front axle 3 is'pivoted as by the king bolt5 in order that thefront wheels 6,- may be turned to guide the vehicle in either direction.

The rear driving axle 7, is journaled in suitable bearings. 8, mountedupon the rear end portion ofthe truck frame. A. seat 9 may be supportedabove the truck frame as by the brackets 10 which extend upwardtherefrom. The rear wheels 11 are fixed in a suitable manner upon thedriving axle 'Z.

The operating lever 13 is pivotally mounted, intermediate itsextremities, upon the truck frame as by the spaced, inverted U shapedbrackets l.l-,-which are rigidly mountcd upon the frame HII'ClCXi-Gllflupward there from. A suitable hand piece 15 may be provided upon theupper end of the lever for operating the same.

The lower end of'the operating lever is pivotally connected, asby thelink 16, with the depending end portion 17 of the l.- shapedtransmission rod 18 which is slidably mounted within the bearing 19,pivoted as at 20 to the frame. i

a plan section on the line 2-2,

mounted through carried at the rear I end of the transmission rod 18 and1s provided with the upper. and lower, oppositely disposed rackportions22 A slide frame 21,of shape, if

and 28 respectively arranged to alternately engagethe ratchet gear 21which is fixed upon the driving axle 7.

. Slotted guide pl tesf 25 are mountedupon opposites'ides of the slideframe enclosing the ratchet gear within said frame and as surlng contactwlth, elther of the rack portions as thetransmission rod is moved for- Iward and backward through. the operation ofthe operating lever. l

The operation of t vious from the above description and'the accompanyingdrawing. In theposition shown in Fig. 1, the operating lever is beingmoved rearward as indicated by the arrow.

It will be seen that this rearwardmovement ofthe operating lever will,through the link he device will be ob 16,.pull forwardly upon thedepending end if I 17 of the transmission rod, rocking the bearing 19 tohold the upperrack 22 in engagement with the ratchet gear as the slideframe 21 is moved forward by the forward movement of thetransmissionrod, thus rotating the driving axle 7 forward. p

Upon reversig the movement of the operating lever, the bearing 19 willbe rocked in the opposite direction, rocking the transmission rod upwardto bring the lower rack- 23 into engagement with the ratchet gear,continuing the forwardrotation thereof as the slide frame is movedrearward. As the operating lever is thus oscillated alternately backwardand forward, the

racks 22 and 23 Will. be alternatelymoved,

into engagement with the ratchet gear, con tinuously rotating saidratchet gear, and with it the driving axle, to propel the ve hicleforward. a r

If it is desired to throw the driving mechanism into neutral position,the operating lever is moved, rearwardly to the limit of its movement,bringing the racks entirely out of engagement with the ratchet gear,holdf ing the blank portion of the slide frame in engagement with thegear.

I claim: p

1. A hand propelled vehicle includinga traction wheel, a gear carriedthereby, a

pivoted bearing, a transmission rod slidably the bearing and providedwith a depending 11,0 forward end port1on, a. slide frame carried at therear end of the lil'illlfillilbfsiml red, and having SPiiCQtl met:

portions and an operating lever opel'atively vennei-leil to thedepending portion of the tl'ilDSll'llSSlOJl red for reciprocating thetransmission rod and rocking the hearing to 211- ternately engageopposite sides of the gear with the rack portions. I

2 A hand propelled vehicle including a traction Wheel, a gear carried.thereby, a

pivoted bearing, ZLlJIiIDSmlSSlOII rod sliclably mounted through thebearing and provlded .1 ssess with an angular fol-mil end portion, aslide ilmme carried zitthe rear end 01: the trainsmission'rod, andhaving spaced rack poi-- tions, an operating lever, and :1 linkconnectwith the rack portions.
